Impact of Geography and Resource Availability on Wildlife Evolution and Diversity

This document explores the multifaceted factors affecting wildlife, focusing on geography, resource availability, and the intricacies of animal interactions. It delves into how geographical features influence natural selection, evolutionary processes like allopatric speciation, and adaptive radiation. It highlights the significance of food availability, nutritional strategies across various organisms, and the defenses plants and animals use to survive. The piece also addresses endangered species and the repercussions of extinction on ecosystems and biodiversity.
